	A ''grammar'' is an object in the Java Speech API that indicates what words a user is expected to say and in what patterns those words may occur. Grammars are important to speech recognizers because they constrain the recognition process. These constraints make recognition faster and more accurate because the recognizer does not have to check for bizarre sentences.		A ''grammar'' is an object in the Java Speech API that indicates what words a user is expected to say and in what patterns those words may occur. Grammars are important to speech recognizers because they constrain the recognition process. These constraints make recognition faster and more accurate because the recognizer does not have to check for bizarre sentences.

	The Java Speech API 1 supports two basic grammar types: rule grammars and dictation grammars. These types differ in various ways, including how applications set up the grammars; the types of sentences they allow; how results are provided; the amount of computational resources required; and how they are used in application design. Rule grammars are defined in JSAPI 1 by [[JSGF]], the Java Speech Grammar Format~~. The newer JSAPI 2 supports the more recent [[SRGS]] format. JSAPI 2 does not offer support for dictation~~.

	Speech synthesizers can make errors in any of the processing steps described above. Human ears are well-tuned to detecting these errors, but careful work by developers can minimize errors and improve the speech output quality. While the Java Speech API 1 relied on the [[Java Speech Markup Language\|Java Speech API Markup Language]] (JSML), the newer release utilizes [[Speech Synthesis Markup Language\|SSML]] to provide many ways for you to improve the output quality of a speech synthesizer.

The Engine interface encapsulates the generic operations that a Java Speech API-compliant speech engine should provide for speech applications.

	Speech applications can primarily use methods to perform actions such as retrieving the properties and state of the speech engine and allocating and deallocating resources for a speech engine. In addition, the Engine interface exposes mechanisms to pause and resume the audio stream generated or processed by the speech engine. ~~Streams~~ can be ~~manipulated by the AudioManager~~. The Engine interface is subclassed by the Synthesizer and Recognizer interfaces, which define additional speech synthesis and speech recognition functionality.
